A single-phase 220V input frequency converter designed to drive a three-phase motor (motor connection must be converted to delta type). Features a four-digit digital display for clear reading of operational data, including radiator temperature, output current, DC bus voltage, motor speed, and operating frequency. Output frequency range: 1.0–99.0Hz. Utilizes SVPWM modulation with an 8.0kHz carrier frequency to improve output voltage efficiency. Adjustable V/F curve settings allow customization of compensation frequency and voltage ratio, optimizing energy usage, reducing motor heat, and extending the service life of both motor and converter. Delivers high torque at low frequencies. Converts single-phase 220V input to three-phase 220V output for energy-efficient operation. Includes built-in protection against overheating and overvoltage.
